Relief at last!

I contacted Sussex Solar as a Trusted Trader 6 months ago as an elderly relative was being hounded & scammed by solar / green energy companies on a regular basis. From the moment I asked for help they have been amazing. The reassurance of speaking to reputable, honest people has been such a relief. They assessed the PV system, advised the best way forward, removing unnecessary/incorrectly installed equipment in a professional manner leaving the system safe at last. The WHOLE team have been amazing. Communication by both phone & email has been patient (steep learning curve on my part!), professional, helpful & transparent - I have felt totally supported through the process and what has been a very stressful period. I cannot recommend them highly enough.

Not a Standard Installation

Our roof was not suitable for the number of solar panels required to provide the required power output. Thinking outside the box, Sussex Solar was also able to install panels on a detached garage roof to make up the shortfall. Along with battery storage, the system is working as specified. Due to some technical issues with our house layout, the installation took a bit longer than planned but they accommodated this without fuss and overcame any difficulties. Great Company to deal with and receive the dedicated personal service one doesn't always get these days.

Sussex Solar finished their three day installation last week. The guys were amazing very focused and discreet. The installation was carried out exactly in the three days allocated with the battery being the last item to be installed. The neatness of all the work and the lack of disruption was brilliant. Would most definitely recommend. We also thought the price was competitive and what we were expecting.

I contracted with the Sussex Solar team to advise on/supply/install a heat pump heating system and batteries. I found their work to be of an extremely high standard, and completed on time. Their team are friendly, efficient and courteous, I have no hesitation in recommending them.

Having selected the system components independently, I contacted three potential suppliers from the manufacturer's approved list and cross referenced with online reviews. All suppliers were small businesses. Of the three, Sussex Solar had the best communications (very good) and were marginally cheaper, while also accommodating the number and type of panels I'd specified, even if the fit was tight on the roof. The installation took 3 days by Sussex Solar's own personnel, who worked efficiently and were very pleasant, even offering to help with moving furniture back after the internal cable installation. As part of the commissioning, Sussex Solar also assisted with the setting up of the Apps and accounts. The only subcontracted element was the scaffold and even then the selected scaffolders were efficient and friendly. There was one small issue with the commissioning, which was quickly resolved within a couple of days, though the system was operational at the end of the 3 day installation. A very satisfactory experience from the initial contact to the final commissioning, a total period of a little over 3 months (which included the G99 application and approval from the DNO).

We decided to replace our aging liquid solar panels with photovoltaic panels, following 18 years of free hot water between March and October. The original panels were maintained by Sussex Solar, and having been so pleased with their servicing it seemed a no-brainer to return to them for the installation of new panels. We were not disappointed. At every step, there was someone knowledgeable and helpful. The installation was efficient and mindful of the construction of the house. The installation team was professional and friendly. Barring the new items, you wouldn’t know that they had been here! We are truly grateful to Charlotte in the office for helping us with any queries and the documentation required for exporting to the grid.

Very good company to use, have used them before, would recommend them to others. Their workmanship is very good and professional, and they were very helpful in installing the app on my phone. They left my house 🏠 in a very clean state. Couldn't fault them one bit.

Sussex Solar was an impressive team, the first supplier I saw, and after searching the market, were best choice for me. They were knowledgeable, helpful, service-focused and patient over a long period from enquiry to final installation. Really nice people to deal with and gave great confidence in a space where many other suppliers are very sales-led. They were service-led and it really makes a difference. Did everything they said when they said they would do it, often before, and couldn’t have been more accommodating.
